Unit tests now work. The linux build was failing saving params
because it was using the changes for QuRT that fake out the
filesystem.

A new poll command was added in accelerometer_calibration.cpp
that needed to be converted to a px4_poll.

Made the logging macros generic so they can be used for multiple targets.

Fixed toolchain_native.mk so err.h is included from src/systemlib for posix.

Reduced debug output for uORB.

In QuRT, this is a long but the variable was being printed with "%d"

Need to cast variable as long and use "%ld"

Using %llu or %lu will break one of the build targets. The "right way"
to print a uint64_t is via the PRIU64 macro defined in C99.

This wasn't defined for the NuttX compiler so it was added to px4_defines.h
for NuttX.

The ROS build included some files that used isfinite vs PX4_ISFINITE.

The AppState class also needed to be supported for ROS.

The warnx and warn calls map to PX4_WARN.
Calls to errx or err genrtate a compile error.

The px4_log.h file implements a new log format:

For DEBUG and INFO:
<level> <msg>

For ERROR and WARN:
<level> <msg> (file filepath line linenum)

The verbosity can be changed by setting the macro to use
either linux_log or linux_log_verbose in px4_log.h

Self leveling

Preflight: GPS check

l3gd20: faster gyro interrupts

The transfer function would previously return error if the receive
buffer length was 0. This appears to be a valid condition for
requesting a measurmement be taken but no data returned.

Added -D__QDSP6_DINKUM_PTHREAD_TYPES__ to makefiles/toolchain_hexagon.mk
so the pthreads functions are properly defined.

There are cross platform issues with the isfinite call that are handled
by PX4_ISFINITE
